Irrotational vector field example | How to prove vector is irrotationalTag:How to prove vector is irrotational | irrotational vector field proof | brightfutu...A vector or vector field is known as solenoidal if it's divergence is zero.This ... In this video lecture you will understand the concept of solenoidal vectors.Calling solenoidal the divergengeless (or incompressible) vector fields is misleading. The term solenoidal should be restricted to vector fields having a vector potential. Solenoidal implies divergenceless, but the converse is true only in some specific domains, like R3 or star-shaped domains (in general: domains U having H 2dR ( U )=0).18 2 Types or Vector Fields E(x,y,z) = ES(x,y,z) + EV(x,y,z) (2-1) Hence, an arbitrary vector field is, with respect to its physical nature (I.e. the individual contributions of both components), uniquely specified only if its sources and vortices can be identified, in other words, if its source density and vortex density are given. progressive home by homesite lender portal Subscribe to his free Masterclasses at Youtube & discussions at Telegram SanfoundryClasses . This set of Vector Calculus Multiple Choice Questions & Answers (MCQs) focuses on “Divergence and Curl of a Vector Field”. 1. What is the divergence of the vector field at the point (1, 2, 3). a) 89 b) 80 c) 124 d) 100 2. This follows from the de Rham cohomology group of $\mathbb{R}^3$ being trivial in the second dimension (i.e., every vector field with divergence zero is the curl of another vector field). What is special about $\mathbb{R}^3$ which allows this is that it is contractible to a point, so there are no obstructions to there being such a vector field.If you are in 2D and if you want more physical setups, I suggest you consider potential flows.. There are various ways to construct these potential flows which are always divergence free and which satisfy certain boundary conditions..
